Mike & Herman,
Thank you. Both good ideas... and sorry about moving the goal posts
here... but the problem is still becoming clear to me as I think about
it more... Actually, the problem I have with IIF() in these
circumstances is where I want to evaluate more than one expression
within the if() condition... for example,
HLRange = abs( H - L );
ABC = HLRange > Ref( HLRange, -1 ) AND HLRange > Ref( HLRange, -2) AND
HLRange > Ref( HLRange, -3 );
XYZ_Check=IIf(Ref(ABC,-1),1,IIf(Ref(ABC,-2),2,IIf(Ref(ABC,-3),3,0)));
if(XYZ_Check==0)
{
RU1_Check = Open>Ref(Open,-1) AND Open>Ref(Open,-2) AND Open>Ref(Open,-3);
RU2_Check = Close>Ref(Close,-1) AND Close>Ref(Close,-2) AND
Close>Ref(Close,-3);
}
if(XYZ_Check==1)
{
RU1_Check = Open>Ref(Open,-2) AND Open>Ref(Open,-3) AND Open>Ref(Open,-4);
RU2_Check = Close>Ref(Close,-2) AND Close>Ref(Close,-3) AND
Close>Ref(Close,-4);
}
if(XYZ_Check==2)
{
RU1_Check = Open>Ref(Open,-3) AND Open>Ref(Open,-4) AND Open>Ref(Open,-5);
RU2_Check = Close>Ref(Close,-3) AND Close>Ref(Close,-4) AND
Close>Ref(Close,-5);
}
if(XYZ_Check==3)
{
RU1_Check = Open>Ref(Open,-4) AND Open>Ref(Open,-5) AND Open>Ref(Open,-6);
RU2_Check = Close>Ref(Close,-4) AND Close>Ref(Close,-5) AND
Close>Ref(Close,-6);
}
Sorry if this is labouring a point. But I always get stuck by this
structure... I guess I should just use a loop, but I am loathe to if
there is another way.
TIA
